Abstract
The invention provides a filter-press plate for a filter-press unit. The filter-press plate can be used for keeping liquid penetration smoothness of filter cloth, and prolonging the service life of the filter cloth. The plate surface of the filter press plate is provided with small embossments, and diversion areas surrounding the small embossments are distributed in a zigzag form. Compared with the prior art, the filter-press plate has the advantages that the filter cloth is supported sufficiently in longitudinal and latitudinal directions through the diversion areas which are distributed in the zigzag form, and the situation that the filter cloth cannot be supported at a long distance in a certain direction is avoided, so that the liquid penetration smoothness of the filter cloth is ensured, and meanwhile, the service life of the filter cloth is prolonged.
Description
Technical field
The present invention relates to the dehydration of field of sludge treatment, filter plant, and in particular to a kind of filter press plate of press filtration unit.
Background technology
In sludge dewatering treatment, can press during sludge forms the relatively low mud cake of moisture content after filter press dehydration
Leach substantial amounts of pressing filtering liquid.Mud cake can be brought into close contact with filter plate assembly in extrusion process, even if after each metafiltration board component is separated,
Still there is substantial amounts of mud cake cannot come off from filter plate assembly, need the mud cake of artificial output attachment, have a strong impact on equipment
Operating efficiency.
In prior art, uniform intervals are arranged with small convex pillar in filter plate body plate face, when oil cylinder presses, squeeze from mud
Trickle to the osculum at filter plate edge in gap between each small convex pillars of moisture Jing for going out；After moisture thoroughly overflows, oil cylinder pressure release,
Each filter plate is separated, and filter cloth jack-up is prevented filter cloth and filter plate adhesion by small convex pillar.The plate face of filter press plate is main more with circle or square plate
Structure, the effect of small convex pillar originally in order to supporting filter cloth forms drainage channel around small convex pillar simultaneously, but, existing skill
In art due to be limited to process convenience impact, small convex pillar is arranged into scheme as shown in Figure 1, i.e., dotted line I-I,
Small convex pillar is not provided with region shown in II-II, III-III direction, also just without support, the region extends the region filter cloth
In the whole plate face of filter plate, and the water conservancy diversion region parallel with above-mentioned dotted line direction there is also same problem, for convenience
By the referred to as straight-through guiding region in above-mentioned water conservancy diversion region.There is problems with such scheme：The first in pressure-filtering process, corresponding to upper
Stating the filter cloth of straight-through guiding region will be attached in filter press plate plate face, intercept the drain passage of sewage or at least extend sewage
Vent path, increased resistance of water drainage；It two is that in pressure-filtering process, sludge is close to filter cloth and forms dirt at straight-through guiding region
Mud rib, due to the formation of numerous sludge ribs so that mud cake is difficult to be separated with filter cloth, press filtration terminates rear mud cake and is difficult to freely fall
Fall, need labor cleaning, take time and effort；Its three be filter cloth be by Jing, latitude both direction velvet weaving form, in pressure-filtering process
In, the pulling force that direction is subject to is very big, and the pressure very little that another direction is subject to, and such silk weaving stretches uneven, shadow
Ring the service life of filter cloth.
The content of the invention
The invention provides a kind of filter press plate of press filtration unit, can keep the patency of filter cloth transparent liquid, filter cloth is improved
Service life.
To achieve these goals, the technical solution used in the present invention is：A kind of filter press plate of press filtration unit, filter press plate
Small convex pillar is laid with plate face, the water conservancy diversion region around small convex pillar is folding shape arrangement.
Compared with prior art, rolling over the water conservancy diversion region of shape arrangement makes filter cloth obtain enough supports on Jing, latitude direction, no
The unsupported situation of long range on some direction is appeared in, therefore the unobstructed of the transparent liquid of filter cloth is ensured, while also can
Improve the service life of filter cloth.

Specific embodiment
As shown in Fig. 2 a kind of filter press plate of press filtration unit, is laid with small convex pillar 11, small convex pillar in the plate face of filter press plate 10
Water conservancy diversion region 20 around 11 is folding shape arrangement.The water conservancy diversion region 20 of folding shape arrangement makes filter cloth obtain on Jing, latitude direction enough
Support, do not appear on some direction unsupported situation over long distances, in pressure-filtering process, filter cloth is not in attach
Phenomenon in filter press plate plate face, the drain passage of sewage is unblocked, reduces time of filter pressing；Filter cloth is in Jing, two sides of latitude
It is uniform to stretching, therefore the unobstructed of the transparent liquid of filter cloth ensured, and the mud cake suppressed easily is separated with filter cloth, while
Also the service life of filter cloth can be improved.
Embodiment 1
As shown in Figure 3, it is contemplated that small convex pillar 11 it is easy to process, the water conservancy diversion region 20 on filter press plate 10 is at least in level side
It is upwards folding shape arrangement.Here horizontal direction is referred to when filter press plate 10 is in the working condition of vertical, constitutes water
Square to water conservancy diversion region 20 because water flows from top to bottom, if horizontal direction water conservancy diversion region 20 in blocking have sludge
Rib, just blocks the path that water flows downward, therefore at least to ensure that water conservancy diversion region 20 is in the horizontal direction at least folding shape
Arrangement, the defluent path of such water just will not be blocked, though have in sludge rib water conservancy diversion region 20 in the horizontal direction, but
It is that bending part also can be easy to fracture due to stress concentration, washed away because water conservancy diversion region 20 is folding shape arrangement.
Further, the straight-through guiding region unit linking at least two sections of water conservancy diversion region 20 constitutes folding shape arrangement.Should not make
Direct current region is extended in the whole plate face of filter plate, affects the water conservancy diversion effect in water conservancy diversion region 20
Embodiment 2
As shown in figure 4, filter press plate 10 is circular plate-like shape, radial direction and/or circumference of the water conservancy diversion region 20 in the plate face of filter press plate 10
Linking on direction constitutes folding shape arrangement.
Embodiment 3
As shown in figure 5, filter press plate 10 is square tabular, water conservancy diversion region 20 is parallel with the length of side of filter press plate 10 and/or be in
Linking on angle direction constitutes folding shape arrangement.
Embodiment 4
As shown in fig. 6, the size of small convex pillar 11 is different.
The distribution that what is common is that these small convex pillars 11 of 3 embodiments of the above can be random but overall and be
Uniformly, it is so-called uniformly to refer to that the support to filter cloth is uniform enough, and then ensure that filter cloth will not fit i.e. with water conservancy diversion region 20
The permeability of filter cloth is ensure that, and to the support on filter cloth Jing, latitude direction.
Preferably, plastics are provided with the both sides plate face of filter press plate 10 and cross water plate 12, described small convex pillar 11 is arranged on modeling
Expected in the plate face of water plate 12.Small convex pillar 11 is arranged on plastics and crosses on water plate 12, is press-filtered out the water for coming and crosses water plate 12 from plastics
Plate face flows out, and the antiacid caustic corrosion performance of water plate excessively of plastic material is high, is conducive to improving the service life of filter press plate 10.
